Is the blood pressure in the lungs separate from the heart blood pressure?

Is the blood pressure in the lungs separate from the heart blood pressure?

Yes: Oxygen poor venous blood flows to the right side of the heart. It is then pumped into the lungs, and from there goes to the left side of the heart which pumps it into the arteries to the entire body. The commonly measured pressure is the arterial pressure from the lt side of the heart. The pressure in the lungs is from the rt side of the heart, is much lower, and takes an echocardiogram to measure. ...Read more

Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more

When traveling through the heart and blood vessels where is the blood high in oxygen?

When traveling through the heart and blood vessels where is the blood high in oxygen?

Circulation: Blood releases o2 to the tissues and becomes poor in oxygen to travel up to the lungs to capture it in the vessels there. Then it returns to the heart that pumps oxygenated blood to the tissues to be released there and return to the lungs again to get oxygenated. ...Read more

When traveling through the heart and blood vessels where is the blood low in oxygen?

Circulation: Blood releases o2 to the tissues and becomes poor in oxygen to travel up to the lungs to capture it in the vessels there. Then it returns to the heart that pumps oxygenated blood to the tissues to be released there and return to the lungs again to get oxygenated. ...Read more

In a capillary, is hydrostatic pressure the same as blood pressure?

In a capillary, is hydrostatic pressure the same as blood pressure?

No: Blood pressure is measured in large arteries. As arteries branch and get smaller, the pressure gradually drops as well. The hydrostatic pressure in capillaries is a product of and driven by blood pressure in the larger arteries. ...Read more

I wanted to know is blood pressure the pressure in the blood or the pressure in the cuff?

I wanted to know is blood pressure the pressure in the blood or the pressure in the cuff?

Neither: It's pressure in the arteries - the cuff is an indirect measurement. (a direct measurement requires placing a gauge directly into the artery). ...Read more

Systolic blood pressure the upper one?

Systolic BP: Blood pressure is reported as - systolic bp/ diastolic bp. Upper number is the pressure generated when your heart beats or ejects blood from the heart and the lower number is when the heart is at rest between the heart beats. Best BP is 120/80. Systolic BP > 130 and diastolic > 80 need to be followed or treated. ...Read more

What's the risk in lowest blood pressure and high blood pressure too.

What's the risk in lowest blood pressure and high blood pressure too.

Blood pressure: Most common problem with too low of blood pressure is dizziness and possibly passing out. Weakness or fatigue may also occur. Too high of a blood-pressure may lead to vascular disease, stroke, heart disease, kidney disease, etc. ...Read more

Why is blood pressure in artery higher than in vein?

Why is blood pressure in artery higher than in vein?

Higher flow, closer: The arteries get blood directly from the heart, which adds pressure to the blood pool in the left ventricle in order to get it to flow to the body. The veins "hold" blood for the heart to pump, & don't need much force. The arteries also have thicker, stiffer walls than the floppy veins, which allows them to "hold onto" the pressure more. For these reasons, arterial BP is higher than in the veins. ...Read more

Is blood pressure proportional or inversely proportional to the diameter of a blood vessel?

Is blood pressure proportional or inversely proportional to the diameter of a blood vessel?

Blood pressure: if flow is kept constant then decreased cross sectional area of the vessel will necessarily need increased pressure to maintain that constant flow. There are multiple factors involved in the physiology of pressure, flow and resistance ...Read more

Does "high blood pressure" always refer to the narrowing of artery?

Does "high blood pressure" always refer to the narrowing of artery?

No: High blood pressure actually does not refer to narrowing at all. It is a measurement of the forces on the artery. High pressures lead to increased thickness and stiffness of the artery. This may contribute to increased cholesterol deposit in the walls of the artery.And then may also contribute to rupture of the artery (aneurysm) or dissection. ...Read more

How does coarctation of the aorta impact blood pressure in a patient?

Kidney's: Coarctation leads to decreased blood flow in the lower body. The kidney's sense the blood flow and release hormones to regulate blood pressure. If kidney blood flow is low, they release hormones to raise BP and vice versa. And after time, the blood vessels in the body respond to the high blood pressure with abnormal changes of their own. ...Read more

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read more

Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more
